According to the information you provided, your memory and swap is
mostly used.  So hibernate fails are expected.

The question we need to solve now is: what is using up all this memory.
Not much is used up for file cache and so.  There could be a memory leak
somewhere.  But to determine that we need more information.

Please provide the contents of:
- /proc/meminfo
- /proc/slabinfo
